QProcess readLine from qDebug()

louis

Hi,
i started a qt-based qProcess

i connect connect(appProcess, SIGNAL(readyReadStandardError()), this, SLOT(readStandardOutput()));

void AppControl::readStandardOutput()
{
while(m_trmAppProcess->canReadLine())
{
qDebug() << "fromAppProcess: " << m_trmAppProcess->readLine();
}

but this would not work properly.
however i can see that the signal is emitted properly so i run into the readStandardOutput function.

canReadLine() will return false.

how can i get those messages?

readyReadStandardError() is emitted when cerr has data. you need to call setReadChannel to specify you want to read from cerr and not cout.

void AppControl::readStandardOutput()
{
m_trmAppProcess->setReadChannel(QProcess::StandardError);
while(m_trmAppProcess->canReadLine())
{
qDebug() << "fromAppProcess: " << m_trmAppProcess->readLine();
}
}

Thank You. That worked!
